This is a mug that was a prize in the Re:Zero collaboration campaign held at Daily Yamazaki in 2019. It's a valuable item, with only 50 in the world. I've been keeping it, intending to use it someday, but I'm selling it to organize my merchandise. You can buy it immediately. Please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual. If you purchase multiple items at the same time, I will offer a small discount, so please comment beforehand if you'd like to take advantage of this. Also, please understand that if someone purchases the item while we are negotiating, the buyer will be given priority.
